Where is the O2 Sensor located on a 1993 Chevy Caprice Wagon, and is that why the HC Failed the Emission?.

I changed spark plugs and wires, air filter, and I added the Emission stuff to the gas but failed Emission twice!?.

  Oxygen Sensor
  1993 Chevrolet Caprice 5.0L TBI OHV 8cyl
  The Oxygen Sensor is located:
  Under hood, driver side, lower engine area, mounted in exhaust manifold.
  
  Hydrocarbons ( HC ), gasoline is essentially 100% of HC.
  Malfunctions affecting HC are ignition misfire or air / fuel mixture too lean. Check the throttle body injector.
